[0001] This utility model belongs to the technical field of substrate processing equipment, specifically a device for multi-station laser drilling inspection and material stacking integration of substrates. Background Technology

[0002] In the processing of electronic substrates such as PCBs and flexible substrates, laser drilling is a critical process. The drilling accuracy directly affects the quality of subsequent circuit wiring on the substrate. After drilling, the hole size, hole diameter accuracy, and hole wall smoothness need to be inspected. Only after passing the inspection can the materials be stacked and stored.

[0003] In the prior art, the substrate is prone to misalignment due to vibration and displacement of the conveyor belt, which makes it impossible for the inspection camera to accurately align with the drilling area, resulting in "missed hole position" or "hole diameter measurement error", leading to inaccurate inspection.

[0004] Therefore, this utility model provides a device for multi-station laser drilling inspection and material stacking integration of substrates. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that substrates are prone to misalignment due to conveyor belt vibration and displacement, which causes the inspection camera to be unable to accurately align with the drilling area, resulting in "missed hole positions" or "hole diameter measurement errors" and thus inaccurate inspection.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a multi-station laser drilling inspection and material stacking integration device for substrates, including a base plate 1. An integration mechanism is mounted on the base plate 1, comprising: a laser drilling assembly, disposed on the top of the base plate 1 for drilling holes in the substrate, receiving commands from a central control system, and performing laser drilling operations on the substrate according to preset hole diameter and hole position coordinate parameters; and a clamping assembly, including a pair of sliding grooves 2 symmetrically located on both sides of the top of the base plate 1 along its length, with a first sliding block 3 slidably connected within each sliding groove 2. A support block 4 is fixedly connected to the side wall of each first sliding block 3, and a first concave frame 5 is connected to each pair of support blocks 4 via a lifting assembly, forming a "concave" shape. The structure is in the shape of a Chinese character and is inverted "U". A sliding groove 6 is provided on the first concave frame 5 to provide a sliding path for the second sliding block 7. The second sliding block 7 is slidably connected in the sliding groove 6. A first L-shaped block 8 is fixed to the bottom of the second sliding block 7. A concave clamping block 9 is fixed to the lateral side wall of the first L-shaped block 8. A detection camera 10 (Hikvision MV-CA050-10GM) is fixed to the bottom of the first concave frame 5, and is fixed in the center of the bottom of the first concave frame 5. The lens faces the substrate area below and is equipped with a strip laser light source. An adjustment component for moving a pair of second sliders is provided on the top of the first concave frame 5. A moving component is provided on the base plate 1 for moving the first concave frame 5.

[0018] The lifting assembly includes a support block 4 with an electric push rod 11 fixed to the top, which provides power for the lifting and lowering of the first concave frame 5, and realizes the smooth lifting and lowering of the telescopic end. The telescopic end of the electric push rod 11 is fixed to a rectangular block 12, and the side wall of the rectangular block 12 is fixed to the side wall of the first concave frame 5. A rectangular hole 13 is provided on the support block 4, and one vertical end of the first concave frame 5 is slidably connected in the rectangular hole 13 to prevent the first concave frame 5 from deviating when it is lifted and lowered.

[0019] The adjustment assembly includes a first concave frame 5 with a second concave frame 14 fixed to the top, which has a "U" shaped structure and an inverted "U" shape. The second concave frame 14 has a first motor 15 fixed to the bottom side, and the output end of the first motor 15 is provided with a drive rod 16.

[0020] The bottom of the drive rod 16 is fixedly connected to the adjusting rod 17, which can rotate synchronously under the drive of the first motor 15, and transmit the rotational motion of the motor to the adjusting rod 17. Both ends of the adjusting rod 17 are rotatably connected to the connecting rod 18 through the first rotating shaft. The end of the connecting rod 18 away from the adjusting rod 17 is rotatably connected to the top of the second sliding block 7 through the second rotating shaft. The rotation of the adjusting rod 17 can be smoothly converted into the linear motion of the second sliding block 7.

[0021] The moving component includes a second L-shaped block 19 fixed to the side wall of the base plate 1, a second motor 20 fixed to the side wall of the second L-shaped block 19, a threaded rod 21 rotatably connected between the sliding groove 2 and the groove wall, and one end of the threaded rod 21 passes through the side wall of the base plate 1. The output end of the second motor 20 is drivenly connected to the threaded rod 21.

[0022] During operation, by fixing the inspection camera 10 to the bottom of the first concave frame 5 and moving it simultaneously with the substrate, the inspection camera 10 can be precisely moved to the shooting position according to the coordinates of the drilling area of ​​the substrate, ensuring that the center of the camera lens is aligned with the center of the drilling area, thus completely solving the problems of incomplete inspection coverage and missed hole detection caused by conveyor belt offset.

[0023] A pair of material stacking holes 22 are provided on the base plate 1, and a pair of material stacking buckets 23 are detachably connected to the bottom of the base plate 1 by a set of bolts.

[0024] During operation, without the need for additional sorting stations or transfer paths, the clamping components can directly move qualified substrates to the "qualified stacking hole 22" and unqualified substrates to the "unqualified stacking hole 22" based on the inspection results, achieving a seamless connection of "inspection is sorting, and sorting is stacking". Compared with the traditional process of "inspection first, then transfer and sorting, and finally stacking", this simplifies the process and improves work efficiency.

[0025] Working principle: When testing is required, the second motor 20 (moving component) starts, and its output end drives the threaded rod 21 to rotate in the sliding groove 2. The threaded rod 21 drives the first sliding block 3 to move laterally along the sliding groove 2. The first sliding block 3 drives the first concave frame 5 to move towards the substrate through the support block 4. The electric push rod 11 (lifting component) starts, and its telescopic end pushes the rectangular block 12 upward. The rectangular block 12 drives the first concave frame 5 to slide vertically along the rectangular hole 13 of the support block 4, so that the height of the concave clamp 9 matches the thickness of the substrate. The first motor 15 starts, and its output end drives the drive rod 16 to rotate. The drive rod 16 synchronously drives the adjusting rod 17 to rotate. The two ends of the adjusting rod 17 pull the connecting rod 18 through the first rotating shaft. The connecting rod 18 pushes the second sliding block 7 to slide towards each other in the sliding through groove 6 of the first concave frame 5 through the second rotating shaft. The second sliding block 7 drives the L-shaped block at the bottom to slide towards the concave frame 5. The clamping blocks 9 move synchronously until a pair of concave clamping blocks 9 are aligned with the edge of the substrate, completing the adjustment of the clamping distance. The moving component drives the first concave frame 5 to move towards a pair of stacking holes 22. During the movement, the lifting component keeps the height of the first concave frame 5 stable. During the movement, the inspection is completed. If it is a qualified substrate, it moves to the stacking hole 22 for placing qualified materials; if it is a defective substrate, it moves to the stacking hole 22 for defective materials. The first motor 15 reverses and drives the concave clamping blocks 9 to slide back and forth to release the substrate. The substrate falls into the stacking bin 23 below through the stacking hole 22. After the substrate is released, the moving component drives the first concave frame 5 back to the initial position, the lifting component drives the first concave frame 5 to descend, and the adjusting component drives the concave clamping blocks 9 to reset to the initial distance, waiting for the next substrate to be processed, and entering the next work cycle. The first motor 15 and the second motor 20 are both stepper motors.

[0026] The central control system sends an "imaging trigger signal" to the detection camera 10. The camera continuously captures images at a frame rate of 120fps. The captured image data is transmitted in real time to the image processor via the GigE gigabit network port. The image processor uses the "Canny edge detection algorithm" to extract the edge contour of the drill hole in each frame image, and then uses the "least square circle fitting algorithm" to calculate the actual diameter of the drill hole: for each drill hole, the diameter measurement values ​​at 3 different angles are taken, and the average value is taken as the final hole diameter value. Compared with the preset standard value, the hole diameter values ​​of all drill holes are within the preset standard value ±0.005mm; the hole position deviation of all drill holes is ≤0.01mm; there are no defective drill holes with any markings on the substrate (burrs, foreign objects, scratches are all within the allowable range). When all the above conditions are met, the central control system determines it as "qualified" and plans the movement path to the "qualified stacking hole 22".

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
